Free checkers show you a signal, not a picture. Each covers one or two platforms — none checks accuracy, competitor gaps, or what to fix.
There are several free tools that claim to check your AI visibility — from Semrush’s AI search visibility feature to manual Perplexity and ChatGPT queries. I tested them across real sites to see what each actually measures, what gaps they leave, and whether the results are actionable. Short version: free checkers show you a signal, not a picture. Here’s what each one found — and where each falls short.
This post covers free, one-off checkers. If you’re looking for paid ongoing AI visibility tracking platforms, that’s a different category — see the best AI visibility tools instead.
AI visibility is how often — and how accurately — your brand appears in AI-generated answers across platforms like ChatGPT, Perplexity, Google AI Overviews, and Gemini. It’s not the same as SEO rankings, and it can’t be measured with the same tools. For a full definition, see what is AI visibility.
The challenge with free checkers: AI visibility spans multiple platforms, each with different retrieval mechanisms. Most free tools cover one. That’s where the gaps start.
The best AI visibility checker for your situation depends on which platform you’re trying to monitor and how much time you have. Here’s what I found across all eight.
Semrush AI Search Visibility Checker
What it checks: Semrush’s Position Tracking tool includes an AI Overviews column showing whether your tracked keywords trigger a Google AI Overview — and whether your domain appears in it. Free accounts get limited keyword tracking; Semrush Pro unlocks full coverage.
What I found:For keyword sets with informational intent, Semrush surfaced AIO presence accurately, matching what I observed manually in Google. The data is query-level: you can see which specific keywords trigger an AIO and whether your site is cited. That’s genuinely useful for SEO teams already working inside Semrush.
What it misses: Google AI Overviews only. ChatGPT, Perplexity, Gemini, and Bing Copilot are not tracked. The tool shows whether you appear — not what the AIO says about you. Accuracy checking is absent. No competitor gap view on the free tier.
Best for: Existing Semrush users who want Google AIO inclusion data layered onto their current keyword tracking workflow.
Ubersuggest AI Search Visibility
What it checks:Ubersuggest has added AI Overview detection to its rank tracking. For keywords you’re monitoring, it flags whether a Google AI Overview appeared in results.
What I found:Ubersuggest’s AIO detection is functional but less granular than Semrush. It shows whether an AI Overview was present for a query — but doesn’t tell you whether your site was specifically cited in it. That’s a critical gap: an AIO present does not mean you’re in it.
What it misses:No citation attribution — you can’t tell from Ubersuggest alone whether you’re actually being cited or just nearby. No Perplexity, ChatGPT, or Gemini coverage. Accuracy not addressed.
Best for:Ubersuggest users who want a rough signal on how often AI Overviews appear for their tracked keywords — not for checking whether they’re cited.
Wix AI Visibility Overview
What it checks:Wix offers an AI Visibility Overview dashboard in its site analytics for Wix-hosted sites. It shows how often your content is referenced by AI platforms based on Wix’s internal tracking layer and AI-driven traffic patterns.
What I found:For Wix sites with real traffic, the dashboard surfaces useful data on AI-attributed visits and content referrals. The framing is more analytics-oriented than audit-oriented — it shows you what arrived, not whether you’re being cited for specific queries.
What it misses:Only available on Wix-hosted sites. Platform coverage is limited. Doesn’t show citation accuracy or competitor gaps. No actionable fix recommendations.
Best for:Wix site owners who want a quick AI traffic overview from inside their existing dashboard. Not usable if you’re not on Wix.
Manual ChatGPT Query Method
What it checks: Running your core queries directly in ChatGPT — with Browse enabled and without — to see whether your brand is mentioned, what it says, and how accurate the description is.
What I found: This is the most accurate ChatGPT-specific check available. It shows you exactly what ChatGPT generates about your brand in real time. Browse mode and training-data responses often differ — testing both is essential. The limitation is scale: manual testing covers 10-20 queries, not hundreds.
What it misses:No tracking over time. No competitor comparison. Time-intensive at any meaningful scale. Results can vary by session — ChatGPT’s responses aren’t perfectly consistent.
Best for: Any business that wants a ground-truth snapshot of what ChatGPT says about them right now. The fastest first check, and the most honest one. See also: how to get mentioned by ChatGPT.
Manual Perplexity Query Method
What it checks: Running your core queries in Perplexity to check whether your site is cited, which pages are pulled, and what text is extracted and displayed alongside your citation.
What I found: Perplexity is the most transparent platform to audit manually. It shows its sources explicitly — you can see which exact pages are cited, what text was extracted, and how your brand is described in the synthesized answer. That level of visibility makes it easier to identify inaccuracies than any other platform.
What it misses: Same limitations as ChatGPT manual — no scale, no historical tracking, no competitor comparison. Perplexity Pro shows fuller source attribution on some queries; free accounts see limited source data.
Best for:Anyone who wants to understand not just whether they’re cited, but which specific pages are being pulled and what content is being extracted from them. See also: how to get cited by Perplexity.
Manual Google AI Overviews Method
What it checks: Running queries in Google (in an incognito window) to observe whether an AI Overview appears and whether your site is cited within it.
What I found: Reliable for individual query checks. Incognito mode reduces personalization bias — what you see is closer to what a cold user sees. AIO activation varies by query type: high for informational queries, lower for commercial and navigational ones. Reading the AIO text directly lets you catch accuracy issues.
What it misses: No systematic tracking. AIO inclusion changes frequently. What you see today may differ from what a buyer sees in a week. This method is a point-in-time snapshot, not a monitoring system.
Best for: Quick manual checks on high-priority queries. Best combined with Google Search Console for scale and historical data.
Amplitude AI Visibility
What it checks:Amplitude is a product analytics platform — not an AI visibility checker in the brand citation sense. If you’ve searched for “Amplitude AI visibility,” you’re likely looking for one of two things: Amplitude’s AI-powered analytics features (which help analyze user behavior and product data), or its attribution tools for tracking which traffic sources — including AI-referred traffic — convert in your product.
What I found:Amplitude doesn’t offer a standalone checker for brand citations in ChatGPT, Perplexity, or Google AI Overviews. It’s a behavioral analytics platform. If you’re trying to track AI-referred traffic in your conversion funnel after users arrive, Amplitude can help — but that’s a different layer than checking whether you’re being cited in the first place.
What it misses:It’s not designed for this job. Amplitude measures what happens on your site after users arrive. AI visibility is about whether they find you through AI search before they arrive.
Best for: Product and conversion analytics downstream. For AI citation visibility, use the other tools in this list.
Google Search Console (AIO Performance Data)
What it checks:Google Search Console now surfaces AI Overviews data in its Performance reports. You can filter by “Search type: AI Overviews” to see impressions and clicks from AIO-featured results specifically — for queries where your site was cited.
What I found:This is the most underused free AI visibility tool available — and the most authoritative for Google AI Overviews. Unlike third-party tools that estimate AIO presence, Search Console shows actual impression and click data from Google for queries where your site was specifically included. It’s real data, not an approximation.
What it misses:Google AI Overviews only — ChatGPT, Perplexity, and Gemini are not covered. The AIO data filter is still rolling out and may not be available in all accounts yet. You can see that you were cited, but not what the AIO said — you’d need to run the query manually for that.
Best for:Every site owner. Set this up first. If you’re only going to use one free method, start with Search Console — the data is authoritative, free, and already available if you’re verified.
Free AI visibility checkers show you a signal, not a complete picture — they check one or two platforms but miss accuracy issues, competitor gaps, and actionable fixes.
Across all eight tools, four gaps came up consistently:
Platform coverage. Every free tool covers at most one or two platforms. Your buyers may be asking questions across ChatGPT, Perplexity, Gemini, and Google AIO simultaneously — and free tools give you no view into most of them.
Accuracy.Free tools show whether you appear. They don’t check what AI says about you. A citation that gets your specialty, location, or positioning wrong isn’t a win — it’s a problem you don’t know you have.
Competitor gaps.None of the free tools show where competitors are being cited that you’re not. That’s often the most actionable insight: knowing which queries you’re losing.
Actionable fixes.Free tools surface the presence or absence. They don’t explain why you’re absent or what to change. The signal is useful. The roadmap requires analysis.
If you need cross-platform coverage — ChatGPT, Perplexity, Google AIO, and Gemini — with accuracy checking, competitor gap analysis, and a prioritized fix plan, that’s what a professional audit delivers.
A professional audit makes sense when:
- You’re losing business to competitors who appear in AI answers and you don’t
- You’re being cited, but AI platforms are describing your business inaccurately
- You’ve made technical or content changes and want to measure their actual effect
- You’re entering a new market and need to establish AI presence strategically
Free checkers are a starting point. An audit is a decision tool.
Need cross-platform coverage?
The audit covers ChatGPT, Perplexity, Google AI Overviews, and Gemini — with platform-specific citation analysis, accuracy review, competitor gap mapping, and a prioritized action plan.
Book an AI Visibility Audit →Is there a free AI visibility checker?
Yes — several. Google Search Console's AIO performance filter, Semrush's AI Overviews tracking, manual ChatGPT and Perplexity queries, and Ubersuggest's AIO detection are all free or partially free. The limitation: each covers only one or two platforms, and none checks whether what AI says about you is accurate.
Does Semrush check ChatGPT visibility?
No. Semrush's AI visibility features track Google AI Overviews only. ChatGPT, Perplexity, and Gemini are not currently covered by Semrush's platform.
How accurate are free AI visibility tools?
They're accurate for what they measure, but narrow. Platform-specific tools reliably detect AIO appearances on that one platform. What they miss — cross-platform coverage, citation accuracy, competitor comparison — is often the most strategically important information.
Can I check my Perplexity visibility for free?
Yes — manually. Run your core queries in Perplexity and observe whether your site is cited. Perplexity shows its sources explicitly, making manual auditing relatively transparent. There's no automated free tool that tracks Perplexity citation frequency at scale.
What's the difference between a free AI visibility checker and a professional audit?
Free checkers give you a one-platform snapshot with no context on accuracy, competitors, or what to fix. A professional audit covers all major AI platforms, checks what AI is actually saying about you, identifies competitor gaps, and delivers a prioritized action plan.
